[Langerhans' cell histiocytosis of the liver. Differential diagnosis of a rare chronic destructive sclerosing cholangitis].

We report on the difficult differential diagnosis of liver involvement in disseminated Langerhans' cell histiocytosis (LCH). Three years after treatment of LCH involving the skull and pelvic bones, an 18-year-old girl presented with abdominal pain and cholestatic liver disease. At this time, liver biopsy showed portal infiltrates which were diagnosed as chronic non-suppurative destructive cholangitis.

First-line ritonavir/indinavir 100/800 mg twice daily plus nucleoside reverse transcriptase inhibitors in a German multicentre study: 48-week results.

Objectives: To evaluate safety and efficacy of the protease inhibitor combination ritonavir/indinavir 100/800 mg twice daily plus 2-3 nucleoside reverse transcriptase inhibitors (NRTI) in antiretroviral-naive patients.

Methods: Within this open-label, uncontrolled multicentre trial, antiretroviral-naive patients (n = 57) with median baseline HIV-RNA of 308,000 copies/mL (range 170-3.01 million copies/mL) and median CD4 cell count of 50 cells/microL (range 0-853 cells/microL) were started on 2-3 NRTIs plus ritonavir/indinavir 100/800 mg twice daily.
